Title: Feature amount evaluating method in graphic recognition
Inventor: ORITA MIYAHIKO
IPC: G06K9/70
Filed: 1983-12-29
Abstract: PURPOSE:To attain identification by applying the best evaluating method (discrete distribution) in the split performance to a category even if an object category is in any distribution state so as to evaluate and select the proper feature amount of plural categories. CONSTITUTION:The evaluation is conducted along the internal operation of a discrete distribution calculating section 9 of a feature amount F2. A category managing section 15 generates two category combinations from Ca-Cf so as not to be duplicated to a feature amount distribution data 14 of each category stored in a form compressed into a mean value and a standard deviation. The distribution data (mean value and standard deviation) of the two categories are transferred to a inter-distribution distance calculating section 16. A category combining and management section 15 repeats the operation until all the combinations of categories are outputted at each start command from a discrete propriety discriminating section. Thus, a proper feature amount is evaluated and selected and the identification is attained to plural given categories.

Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To detect leakage of liquid surely in the early stage by forming a transparent or translucent tubular casing, irradiating a light from an irradiation circuit, receiving the reflected light by a light receiving circuit and then detecting variation in the quantity of received light. SOLUTION: A transparent or translucent tubular casing 1a having circular or regular polygonal cross-section and the opposite mirror or smooth side walls encases a light source circuit 2 for irradiating the side wall of the casing 1a, a circuit 3 for receiving the light reflected on the side wall of casing 1a, and a circuit for detecting variation in the qualtity of light being received by the circuit 3 and producing a detection signal. An irradiating light L emitted from an emission transistor, for example, is reflected on the smooth side wall of casing 1a and the reflected light L* is received by a light receiving transistor. When a leaked liquid reaches the outer surface of side wall, the irradiating light is not reflected thereat but transmitted. Since the quantity of light to be received is reduced, leakage of liquid can be detected.
